STILL.'

Application ined nay' 1,A

.Myi inventionl relates to the art of rel iningoil, and has for itsobject the producl tion of an apparatus which will more'etiicientlyperform the necessary functions described in my prior-copendingapplication Serial No. 376,103,led April 23, 41920. In said application,I disclosed a shelf to hold a catalyzer such as coal or carboniferousmaterial. .In the present case I present a complete still structure ororganization with the shelil suspended adjustably from 'above so that it'is ou'D of contact with the walls of the still,'and can be adjusted bythe operator during a run. (This is the result -ot' my discovery thatthe distance at which-the'fcarbonaceous material is held from thebetteln of the still has a marked eii'ect upon the 4results Obtained andthat the critical distance at which the most desirable results th san;

are obtainedv is not always the same, varylng for diiferentlkmds ot'011,` differences 1n gravity, and according to circumstances 1n-Acideztt to the process itself. 'llo meet these variable conditions lmake the shelf adjust'- able at the will ot' the operator Withoutopening the retort, during operation. Among the advantages gainedby'this form'of construction are, that the Weight ofthe shelf` andcatalyzer are supported separately from the vstili body, therebyrelieving the latter of considerable strain, which'is important it' anyvacuum forms in the still tending to collapse it; also by permitting theshelf to be raised in cleaning, to give room `for men to 'Work in anupright position.

In the accompanying drawings illustratingrthe inventonz- 1g. 1 is alongitudlnal Vertical section of 1920. Serial No. 393,424.

Fig'. 2 is a vertical transversdsection; sito Iig. 3 1s a horizontallongitudinal section, showing part of the shelves or screens in p01/sinon;

Figs. 4, 5, 6 and 7 are details of the suspension means. n 45 In thedrawings, l is the body of the still,

2 is the shelf suspended therein comprising a rack haring longitudinalmembers Il and cross members 5 supported from Vertical suspensiondevices 3 comprising rod and 5o chain bonstruetion'shown in detail inFigs. 4, 5, 'G and 7. On the shelf 2 is a series of screens 6 extendingfrom end to end oit' the shell and of such dimensions as to be possibleof Withdrawal-and insertion through 55 the usual manhole.

In operation the catalyze'r 6 employed as described in the aforesaidapplications is placed upon the screens 6, and hangs immersed in the oilat a depth determined hr the operator by means o the lmnrl-wlieelsleneaththe .screens is suspended a pan T to ca tch falling particleswhich would othcr- Wise clog and burn onto the .walls'of the still. *35What I claim is:- l

The combination ot' a still for cracking hydrocarbons and a rack,' meansit'or suspending said rack within the still and means for'adjnsting thevertical position of said 'm rack, said adjusting means being operablefrom Without 'the still, and stutiing 'noxes through which-stud.snspendingl means pass.

i. In testimony whereof I hereunto alix my signature.
